VB (Vapor Barrier) - Fluid-Applied Air & Water-Resistive Barrier and Water Vapor Barrier

VB is a fluid-applied air and water-resistive barrier that stops air and water leakage in cavity wall, masonry veneer construction, as well as in stucco, EIFS and most other building wall assemblies.

Features

• No air leakage or water intrusion between the
  sheathing and R-Guard VB - stable under air and
  wind pressure loads.
• Fast and easy installation reduces labor costs.
• Won’t tear or lose effectiveness when exposed to
  weather during construction (up to 6 months)

OVERVIEW

Once on the substrate, the easily applied liquid quickly dries into a rubberized, highly durable, water-resistant membrane. R-Guard VB performs the function of both a vapor barrier and an air/water resistive barrier. Spray-grade R-Guard VB is ideal for special construction types that require protection from the passage of air, liquid water and water vapor. R-Guard VB reduces heating and cooling costs and lowers the risk of mold and mildew. Compared to self-adhered or mechanically fastened sheet wraps, easy-to-use R-Guard VB provides superior protection against penetration of liquid water and water vapor. Use R-Guard VB as a high-performing water-resistive barrier, vapor barrier, or as part of a continuous building-wide air barrier system. The durable membrane conforms and adheres to common building surfaces and is compatible with most paints, sealants and self-adhered waterproofing or air barrier components. Appropriate for vertical, above-grade applications to exterior sheathing, CMU, cast concrete and most other common building materials.
